REAGENT FOR INCREASING PRODUCTIVE CAPACITY OF BED AND METHOD FOR DEVELOPMENT OF OIL DEPOSITS WITH USING THIS REAGENT Russian patent published in 1998 - IPC

FIELD: oil production industry. SUBSTANCE: reagent for increasing productive capacity of oil bed represents mineral systems consisting of activated by grinding finely dispersed natural minerals and finely dispersed particles produced due to wearing of components of grinding machines. Method for development of oil deposits is intended for intensive action upon nonuniform flooded oil beds and it includes flooding and injection of water together with mineral reagent and/or injection of water together with mineral reagent and co-reagent. According to method, used in function of mineral reagent is mineral system including activated by grinding finely dispersed natural materials and finely dispersed particles produced due to wearing of components of grinding machines. Water containing mineral system and water containing co-reagent is injected successively or simultaneously. Application of aforesaid method and reagent improves processes of flocculation and filtration in oil bed. EFFECT: higher efficiency. 4 cl, 3 tbl, 3 ex
